Description
This dataset provides detailed quarterly market volume data for Plug-in solar device (balcony power plant) in Germany for the period Q1/2021 to Q4/2031. Plug-in solar devices, also known as balcony power plants, are plug-and-play photovoltaic systems with up to 800 VA inverter output that feed solar power directly into the household grid via a socket; the data covers devices on balconies, facades, garages, carports and in gardens, excluding associated battery storage and permanently installed rooftop systems. The data is broken down into the four main construction segments and is also available as a total market figure. Forecasts are based on a model-based approach using building completions, building permits, renovation rates, and product-specific equipment rates and intensities. The model has been validated using the German market master data register (Marktstammdatenregister) of the Federal Network Agency, supplier surveys and studies by the HTW Berlin University of Applied Sciences. Unit: thousand units. The dataset is delivered in CSV format with all 44 quarters.
